SA Police monitoring ‘hundreds of firebugs’ ahead of bushfire season

South Australian Police have revealed they're monitoring 235 known firebugs as the state prepares for another dangerous bushfire season.

Assistant Commissioner Noel Bamford told 9NEWS that 85 of the arsonists are considered "high-risk," with another 150 considered "low-risk."

"These are the people we assess who may present a risk to our community," Asst. Comm. Bamford said.

Police revealed they will monitor the firebugs as part of "Operation Nomad," which was officially launched in the Adelaide Hills this morning.

The annual campaign aims to reduce the threat of arson and bushfires in South Australia.

"As the harm caused to life and property by bushfires is potentially catastrophic, Operation Nomad concentrates on preventing the deliberate and reckless actions that start these fires," Asst Comm. Bamford said.

"We will maintain a highly visible presence in high risk bushfire areas, with directed patrols watching for any breaches of fire laws.
